It's speculative as it was described that way by Dougal Dixon in his book. I think it's plausible minus the snake like head.

Dougal Dixon's books were great, yes, but in all honesty, they didn't stand the passage of time. Most of them are really outdated now (which doesn't make them less awesome).

Yeah mainly because of what new dinosaurs and evidence we have found now. If he were to update his book it would be great!

Here's a question what were some examples of bipedal or semi bipedal reptiles from the Permian to the Early Jurassic?

Dougal Dixon does have some concepts that outright defy evolutionary logic, but his creativity generally makes up for that.

@BossMan, Jake: There were quite a few, actually. Rauisuchians, ornithosuchids, Euparkeria, Lagosuchus, you name it.

1. Does anyone know what dinosaurs Kaprosuchus preyed on?
2. Also what was the habitat Dimetrodon lived in? I've heard wetland-like areas and dry semi-desert like areas.

Dimetrodon's habitat was closer to the former IIRC. ;)

-Did sauropods had claws on its front and hind lengs or only on hind legs?
-At the moment, is Triceratops a valid species or is only a young Torosaurus?

I would say a valid species since we have a skull that appears to be from a young Torosaurus. I would suggest reading Saurians blog post about it [Link]

Triceratops is the older name in any case, so even if they do turn out to be synonymous Triceratops would take priority over Torosaurus.

As for sauropods: it varied quite a bit. Some of them had claws on all four feet whereas others had the front feet reduced to a toeless "pad" like that of hadrosaurs IIRC.

All derived species seem to have had a single claw on their forefeet and three on their hindfeet, but the foreclaw was very reduced in derived Macronarians.

Relating to something that Incinerox said, If charonosaurus is now most likely parasaurolophous what exactly made the two species different? Was it location and time period?

Pretty much. Charonosaurus lived at least 2 or 3 million years later than Parasaurolophus IIRC and was found in Asia.

Hmm interesting so then if theses two are the same then how come it's still unlikely that Tarbo and Rexy were the same? (Not saying they are as I have no "real" proof of this but it's an idea)

Because I'm pretty sure there are more skeletal differences between Tarbosaurus and T. rex than there are between Charonosaurus and Parasaurolophus.
